Take professional photography to the next level, with the Canon Advanced Two Lens Kit. It includes two Canon EF lenses: a compact, lightweight 50 mm f/1.4 and an ultra-wide 17–40 mm f/4L lens. Both lenses are equipped with an ultrasonic motor that makes it possible to focus on your intended subject automatically in a fast and near-silent manner. For a more precise shooting experience, both lenses also support full-time manual focus. The f/1.4 aperture in the 50 mm lens enables it to produce a gorgeous background blur, as well as deliver impressive low-light performance. The 17–40 mm f/4L lens, which offers outstanding performance, is weather-resistant for use in harsh weather conditions.
